This" invention relates to paving blocks and pavements. I

The paving blocks to -:which the invention applies in .particul'ar yhave flanges at the botfor interlockingsthe blocks.. x 'f in place byffasteners which extend through the flan gesv of theblocks andare anchored in the foundation."` -v TheV fasteners hold the pavement against movement yunder normal conditions but'abnormaltraliic or excessive strains may cause thepaveinent to creep. 4.

An objectief theinvention is tolprovide a paving block whichV maybel securely :fas-l tened in place.

Another; Objectis. capable 'of holding' other paving*y against movement. f Another object isto provide a paving block having a rigid insert thereinf'to distribute strains throughout the block.

Another object is to provide a'pavement Provide @Ming block blocks formed of interlocking-blocks and having a '25 part of said blocks provided With reinforcements to enable the same .to be securely anchored to the foundation and hold the other blocks against lateral movement.

According to the invention, the block has 'a reinforcing platek to resist strains and stresses and transfer the same' to the fastenvers Which secure the block to its foundation.

The block is ordinarily-incorporatedin a pavementin conjunction with other blocks to lhold the same against creeping. Y l vA paving block and a pavement embodying the invention are shown in the accompanying drawing in which the views are as follows: Fig. 1 is a plan view of the block. v Fig. 2 is a perspective vievv thereof. Fig. 3 is a central longitudinal section. Fig. l Y is a central longitudinal section showing two blocks interlocked with each other and secured to a foundation.
